​Some believe that steel tanks are not as good as plastic tanks because they can rust or come apart .Others say plastic tanks contaminate your garden with BPAs & lose its shape.

I have done some research and here is what I've found.yes plastic is cheaper then steel tanks.yes some tanks do say BPA FREE.No not very good looking.yes some evidence of plastic tanks losing its shape but not alot.

steel tanks are more expensive.looks much nicer.Last longer 10 years construction warranty and 20 years corrosion warranty putting my mind at ease.

if you were to put a plastic and a steel rainwater tank next to each other I would always choose the steel tank maybe I'm a sucker for aesthetics and some Bluescope but thats what is in my back yard and i would rather pay more to have that.
